zmult: Zernike coefficient multipliers
In matwey/Rfringe: Rfringe

Description Usage Arguments Details Value Note Author(s) See Also Examples

Conversion factors between normalized and conventional Zernike polynomials.

1	zmult(zlist = zlist.qf)

zlist

A list with named components n, m, t

The list indicates the Zernike polynomial orders to use, in the form returned by makezlist and zlist.qf.

A vector the same length as the components of zlist.

This function is not actually used in the current version of Rfringe, but is included for user convenience.

Zernike, makezlist, zlist.qf.

zcoef <- rnorm(length(zlist.qf$n))
zcoef		# a vector of normalized Zernike coefficients
zcoef*zmult()   # Coefficients in conventional representation
sqrt(crossprod(zcoef)) # This is the RMS error of the wavefront 
			# constructed from these Zernikes
